DNA and RNA Structure

Front

What are the three main components of a nucleotide?

Back

Nitrogenous base, sugar, phosphate group.

Front

What is the role of the phosphate group in a nucleotide?

Back

It forms the backbone of DNA and RNA, linking nucleotides together.

Front

Which nitrogenous bases are found in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G).

Front

What nitrogenous base is unique to RNA?

Back

Uracil (U) replaces Thymine (T) found in DNA.

Front

What type of bond connects the nitrogenous bases in DNA?

Back

Hydrogen bonds.

Front

Where is DNA located in eukaryotic cells?

Back

In the nucleus.

Front

What is the primary function of DNA?

Back

To store and transmit genetic information.

Front

What is the primary function of RNA?

Back

To help in the synthesis of proteins based on the genetic information in DNA.

Front

What is the difference between DNA and RNA in terms of structure?

Back

DNA is double-stranded and has deoxyribose sugar; RNA is single-stranded and has ribose sugar.

Front

What is transcription in the context of DNA and RNA?

Back

The process of copying a segment of DNA into RNA.
